With the reverse lookup feature the PBX does the lookup of calling or called numbers in an external directory so that not each endpoint has to do the same lookup again. The result of the lookup is sent to the endpoints using name id facilities and is stored in the CDRs so that it can be displayed in call lists.

Configuration

For reverse lookup there are two configuration parameters: The LDAP URL as command line parameter at the PBX and a crypted VAR for the LDAP password:

/rl0-url
Command line parameter for the LDAP URL according to RFC 2255
PBX0/RL0-PWD
The VAR for the password

In short the format of the URL is as follows:

ldap(s)://<dn>?<attributes>/<scope>/<filter>/extenstions
dn
The path in the LDAP directory, e.g. dc=entries
attributes
The list of attributes to be returned, e.g. givenname,sn,company
scope
The scope. Could be "base", "one", "sub"
filter
The LDAP filter used for the search, e.g. (metaSearchNumber=+%n)
extentions
Used for the bind name, e.g. bindname=test.com\contacts

Inside the LDAP URL placeholders can be used, which are replaced by the actual information:

%n
The number which should be looked up. It is provided in e.164 international format without prefixed or '+' at the beginning
%u
The H323-Id (SIP URI) of the user on behalf of which the lookup is performed
